Abstract (en)
[origin: EP0401016A1] A blood reservoir (10) is formed with a hard outer shell housing defining at least one blood compartment. A flexible bag (60) is mounted in the outer shell and is connected to the reservoir inlet port to allow blood to directly enter the flexible bag (60). The bag includes two oppositely positioned ends, one of which includes a microporous screen (66) and is situated to lie partially below a minimum level attained by blood in the reservoir (10). The second bag end is substantially open, and includes a porous element (120) partially coated with an antifoaming agent. The coated portion of the element is positioned above a maximum level attained by the blood in the hard shell. The potential of excessive mixing between the blood and air is reduced by controlling the expansion of the bag during blood flow.
